1.2 STHI Overview

The STHI is an SNMP compliant intelligent hub that provides basic management functionality including port and station control, statistical error and trap tracking, and enhanced beacon recovery for a Token Ring LAN. Its front panel TCU (Trunk Connector Unit) ports allow for network connections to either active stations or passive Multi-Station Access Units (MAUs) while its TPIM (Token Ring Port Interface Module) ports allow for ring expansions across a variety of media. Its rear panel HubSTACK ports provide for ring expansion through connections to multiple STH non-intelligent hubs. See Figure 1-1.
